Parkinson's Pen Vibrates to Improve Legibility

Parkinson's disease causes tremors or stiffness that can turn everyday tasks such as eating, brushing teeth or writing into frustrating chores. A few years ago a company called Liftware developed forks and spoons that respond to shaking by steadying the utensil, making it easier enjoy a meal.

Now researchers at Imperial College and the Royal College of Art in London are developing a device called the ARC pen that vibrates to stimulate muscles in the hand. The vibrations could help Parkinson's patients' handwriting - in part by counteracting what's known as micrographia, which causes writing to be small and barely legible. Micrographia is often an early sign of Parkinson's and afflicts about five percent of patients.

Musical Performance Activates Specific Genes

Hey, do you know how to get to Carnegie Hall? Practice, man!

You might also want to switch on your alpha-synuclein gene, and throw in a dual-specificity phosphatase or two. Because a new study finds that these and other genes are activated when professional musicians strut their stuff. The findings are in the journal Nature Scientific Reports.

Mastering an instrument is no easy feat. It requires timing, coordination, emotional interpretation and an ability to integrate information that comes in through the ears, the eyes and the fingers. But what gives rise to musical ability, biologically speaking?

Shipwreck Champagne Reveals Old Wine Secrets

What's better than old wine in new bottles? For scientists, old wine in old bottles, preserved 150 feet down at the bottom of the sea. In 2010 divers were exploring a shipwreck in the Baltic when they discovered 168 bottles of what appeared to be wine. A quick swig from one of the long submerged bottles revealed that the liquid within was actually champagne.

The labels were long gone, but the brandings on the corks revealed the producers to be storied champagne houses, including Veuve Clicquot Ponsardin. The brandings, along with the age of the boat and other items on board helped researchers determine that the champagne was about 170 years old.
